Deploying Azure webapp with Bitbucket pipelines

Need to create a principal which has access to the webapp we want to deploy. To create a principal , first install the Azure CLI, and run the following:

az ad sp create-for-rbac --name MyServicePrincipal

The principal has a role of Contributor by default, so if you have access to the project then it is very likely that the principal will also have access. The roles of a principal can be easily changed via the cli. Note that this also means that a single principal can be used to deploy different apps.

The deployment can be made with the microsoft/azure-web-apps-deploy pipeline. We just need to provide it with the create principal's credentials and the app information where we want to deploy. Refer to the pipeline's page for more documentation.

Once you already have the credentials for the principal you can login with the following command:

az login --service-principal --username ${AZURE_APP_ID} --password ${AZURE_PASSWORD} --tenant ${AZURE_TENANT_ID}

At the time of this writing, the deployment can be tested locally with the following command.

az webapp deployment source config-zip --resource-group ${AZURE_RESOURCE_GROUP} --name ${AZURE_APP_NAME} --src ${ZIP_FILE}
